Find the value of x ?<br><br> A)67<br><br> B)113<br><br> C)77<br><br> D)57
lana [24]

Answer:

<h2>A) 67</h2>

Step-by-step explanation:

The sum of the angles measures at one side of the parallelogram is 180°.

Therefore we have the equation:

x + 113 = 180             <em>subtract 113 from both sides</em>

x + 113 - 113 = 180 - 113

x = 67

Melvin is helping his teachers plan a field trip. There are 255 people going on the field trip and each school bus holds 56 peop
anzhelika [568]

255/56 = 4.55....

You can't have 0.55... buses so you round that up to 1.

Therefore 4+1 = 5 so 5 buses would be the minimum.

Use the substitution method to solve the system of equations. Choose the
sertanlavr [38]
The answer is C because if you substitute in X-6 for the y in the first equation (since X-6 is also equal to y), you get 2x=16 which means x=8. There is only one option where 8 is equal to X, but just to check you can substitute it back into either of the original equations to make sure that y=2.

How do I find if this type of equation has one solution two solutions or no solution 5x^2+14=19 I tried using the b^-4ac method
mash [69]

Answer:

x = 5 and x = -19

Step-by-step explanation:

You're on the right track.  It's the "discriminant" that tells you what you want to know here.  Before starting, arrange the terms of your quadratic in descending orders of x:  5x^2 + 14x - 19 = 0 (Note that I assumed you meant 14x instead of just 14).

Then the coefficients of this quadratic are a = 5, b = 14 and c = -19.

You are referring to the "quadratic formula."  It states this:

      -b ± √(b²-4ac)

x = -----------------------

               2a                                        

So, we insert the a, b and c values as indicated above:

      -14 ± √( 14² - 4[5][-19] )        -14 ± √(196 - 4[5][-19] )        -14 ± √576

x = ----------------------------------- = ---------------------------------- = ----------------------

                 2(10)                                 20                                      20

This comes out to:

x = (-14 + 24) / 2      and     x = (-14 - 24) / 2

or:

x = 5 and x = -19

21.(03.02)<br> If f(x) = 7x – 1, what does f(12) represent?
Mnenie [13.5K]

Answer:

83

Step-by-step explanation:

f(x) = 7x - 1

Put x as 12.

f(12) = 7(12) - 1

f(12) = 84 - 1

f(12) = 83
